Biology:Propleopus

From HandWiki

Propleopus is an extinct genus of marsupials. The genus contains three species: P. chillagoensis from the Plio-Pleistocene, and P. oscillans and P. wellingtonensis from the Pleistocene.[1]

Discovery and naming

The type species Propleopus oscillans was first named under the genus Triclis by Charles Walter De Vis in 1888.[2] Because the German entomologist Hermann Loew had already named the genus Triclis for a robber fly in 1851, Albert Heber Longman named a replacement name Propleopus in 1924, combining the prefix pró (πρό, 'before') with pleopus, the latter in reference to the junior synonym of Hypsiprymnodon moschatus: Pleopus nudicaudatus named by Richard Owen in 1877.[3] In 1978 and 1985, Archer and colleagues named two more species, P. chillagoensis and P. wellingtonensis, and provided a taxonomic revision of the genus.[4]

Description

Speculative life restoration

In contrast to most other kangaroos, and similar to their small extant relative, the musky rat-kangaroo, they were probably omnivorous and quadrupedal.[5] Propleopus is estimated to have weighed around 35.5–47.1 kilograms (78–104 lb).[6]
